Alert dashboard for Prometheus Alertmanager.

Alertmanager UI is useful for browsing alerts and managing silences, but it's lacking as a dashboard tool - unsee aims to fill this gap. Starting with 0.7.0 release it can also aggregate alerts from multiple Alertmanager instances, running either in HA mode or separate. Duplicated alerts are deduplicated so only unique alerts are displayed. Each alert is tagged with names of all Alertmanager instances it was found at and can be filtered based on those tags.

Supported Alertmanager versions

Alertmanager's API isn't stable yet and can change between releases, see VERSIONS in internal/mock/Makefile for list of all Alertmanager releases that are tested and supported by unsee. Due to API differences between those releases some features will work differently or be missing, it's recommended to use the latest supported Alertmanager version.


The unsee process doesn't send any API request to the Alertmanager that could modify alerts or silence state, but it does provide a web interface that allows a user to send such requests directly to the Alertmanager API. If you wish to deploy unsee as a read-only tool please ensure that:

  • the unsee process is able to connect to the Alertmanager API
  • read-only users are able to connect to the unsee web interface
  • read-only users are NOT able to connect to the Alertmanager API


unsee process metrics are accessible under /metrics path by default. If you set the --listen.prefix option a path relative to it will be used.

Building and running

Building from source

To clone git repo and build the binary yourself run:

git clone $GOPATH/src/
cd $GOPATH/src/

To finally compile unsee the binary run:


Note that building locally from sources requires Go, nodejs and npm. See Docker build options below for instructions on building from withing docker container.


unsee can be configured using config file, command line flags or environment variables. Config file is the recommended method, it's also the only way to configure unsee to use multiple Alertmanager servers for collecting alerts. To run unsee with a single Alertmanager server set ALERTMANAGER_URI environment variable or pass --alertmanger.uri flag on the command line, with Alertmanager URI as argument, example:

unsee --alertmanager.uri

There is a make target which will compile and run unsee:

make run

By default it will listen on port 8080 and Alertmanager mock data will be used, to override Alertmanager URI set ALERTMANAGER_URI and/or PORT make variables. Example:



Running pre-build docker image

Official docker images are built and hosted on

Images are built automatically for:

  • release tags in git - cloudflare/unsee:vX.Y.Z
  • master branch commits - cloudflare/unsee:latest


To start a release image run:

docker run -e ALERTMANAGER_URI= cloudflare/unsee:vX.Y.Z

Latest release details can be found on GitHub.

To start docker image build from lastet master branch run:

docker run -e ALERTMANAGER_URI= cloudflare/unsee:latest

Note that latest master branch might have bugs or breaking changes. Using release images is strongly recommended for any production use.

Building a Docker image

make docker-image

This will build a Docker image from sources.

Running the Docker image

make run-docker

Will run locally built Docker image. Same defaults and override variables apply as with make run. Example:

make PORT=5000 ALERTMANAGER_URI= run-docker
